Geek's question: Why there are some OpenVPN
sessions which are disconnected immediately after
established with 0.02MB or less traffic?
We recognize that the cause is from a bug of
OpenVPN Connect for
iPhone. While OpenVPN session is active, OpenVPN
tries to keep the VPN connection forever even if iPhone
is sleeping. But iOS restraints OpenVPN process to be
suspended short time after VPN session establishes. This
repeats many times. So our log records very short-time
OpenVPN sessions from the same IP address.
